Abstract
The utility model relates to a conductive wire which is a high-temperature resisting composite insulation light soft wire suitable for the connection and the wire matching of the inner portion of the instruments and meters of the aviation aerospace craft. The utility model comprises a bundling stranded wire core of metal whose outer portion is wrapped with a teflon film belt and a polyimide coextruded film belt coated with F46. The utility model has the characteristics of small volume, light weight, good softness, electron radiation resistance and good insulating property by adopting the above structure. The requirements on the developing directions of miniaturization, light weight and high reliability of the aerospace products are satisfied.
Description
Technical field
The utility model relates to a kind of lead, designs a kind of light-duty flexible cord of high temperature resistant compound inslation that is applicable to inner distribution of instrument and meter in the aerospace flight vehicle and connecting line especially.
Background technology
At present, be used for the inner distribution of instrument and meter and the connecting line of aerospace flight vehicle, generally adopt individual layer insulation fluoroplastics lead, so volume and weight be bigger, lead is not flexible, and flexibility is poor.Insulating barrier very easily damages during especially this lead raying, and radiation protection ability and poor insulativity are difficult to satisfy the requirement that Aerospace Products develops to miniaturization, lightweight, high reliability direction.
Summary of the invention
In view of there are the problems referred to above in prior art, the utility model is designed to a kind of good insulating, and radiation protection ability is strong and volume is little, lightweight Aero-Space are with the light-duty flexible cord of high temperature resistant compound inslation.
The technical scheme that the utility model is adopted for achieving the above object is: it is made of conductor wire core and two-layer insulation, and conductor wire core adopts metal beam twisted wire core (1); It is characterized in that: conductor wire core has adopted double hyer insulation outward, and this double hyer insulation comprises polytetrafluoroethylene film band (2) and is coated with the polyimide composite film band (3) of F46, reverse successively from inside to outside wrapped forming.
Because the utility model adopts said structure, so it has all reduced about 8% than the conventional wires volume and weight of available technology adopting, and it is good to have possessed flexibility, characteristics such as anti-electron radiation and good insulating have satisfied the inner distribution of instrument and meter in the aerospace flight vehicle and have connected instructions for use with line.
Description of drawings
Fig. 1 is the utility model structural representation and as Figure of abstract
Among the figure: 1. metal beam twisted wire core, 2. polytetrafluoroethylene film band 3. applies the polyimide composite film band of F46.
Embodiment
By shown in Figure 1: conductor wire core of the present utility model adopts metal beam twisted wire core 1.Double hyer insulation is adopted in the periphery of metal beam twisted wire core 1, promptly metal beam twisted wire core 1 outside behind wrapped one deck polytetrafluoroethylene film band 2, and the polyimide composite film band 3 of wrapped one deck coating F46 in the other direction again.
Claims (1)
1. the light-duty flexible cord of high temperature resistant compound inslation is to be made of conductor wire core and insulating barrier, and conductor wire core adopts metal beam twisted wire core (1); It is characterized in that: the outer insulating barrier of conductor wire core is a double hyer insulation, and this double hyer insulation comprises polytetrafluoroethylene film band (2) and is coated with the polyimide composite film band (3) of F46, reverse successively from inside to outside wrapped forming.
